SPECIFICATION forming part of Letters Patent No. 401,911, dated April23, 1889.

Application filed June 20, 1888. Serial No. 277,626. (No model.)

To all whom it may concern.-

Be it known that I, AROHIBALD STEWART, a citizen of the United States,residing at Keota, in the county of Keokuk and State of Iowa, haveinvented certain new and useful Improvements in Scrapers for 'VariousUses; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin .the art to which it appertains to make and use the same.

My invention relates to an improvement in scrapers for various uses.

The object of the invention is to provide a simple and efficient devicewhereby refuse substances may be removed from a surface. It consists inthe scraper-blade, made sub- Similar letters of reference designatecorresponding parts in both figures.

My improvement in scrapers is designed for use in various places. It maybe used for removing snow from pavements; for gathering up refuse,trash, or grain, or other stuff from the surface whereon it may belodged; for cleaning the floors'of stables; for scraping out bins thatcontain different substances; for use in gardens, on elevators, andother places, and In fact, I do not confine my present invention to anyspecific application, but reserve the liberty of using the same whereverits service may be deemed of advantage. The scraper is so constructedthat it is adapted to serve not only as a scraper, but as a hoe. It isso made that it can scrape when being pushed from the operator and whenbeing pulled toward him.

A denotes the handle, which maybe of any suitable length, size, andshape.

B denotes the scraper-blade. It is located substantially at right anglesto the line of direction of the handle, and is secured to the handle inany convenient manneras, for instance, by the braces 11 b, firmlyattached to the blade and'likewise to one end of the handle.

The blade 13 is peculiarly shaped. It is transversely compoundly curved,so that the opposite edges, as a a, project in-diflerent directions fromeach other, as shown in the drawings. Thus it will be seen that onaccount of this compound curvature of the scraper-blade said blade mayserve as a pulling scraper-that is, one which will operate upon thesurface to be scraped when it is drawn toward the person using it; or itmay serve as a pushing scraper-that is, one which will operate upon thesurface to be scraped when it is pushed from the person operating it. Inthis peculiar curved construction of the scraper-blade lies thebeneficial point of my invention. I claim that it will result in anabundance of advantages in actual use over and above those possessed bythe straight scraper. The straight scraper will run over the smallparticles of filth as well as the water and other refuse that mayaccumulate upon the surface that is to be scraped, while the curved formof the scraper-blade will, by passing under the refuse substance, liftit up, as it were, and thus more easily remove it from the surface andmore effectually and thoroughly cleanse the surface. In case my scraperis used for scraping floors that are wet it will be found that all ofthe refuse will be removed, so that the floor will be left nearly dry.

All that is needed to change the scraper from a pulling scraper to apushing scraper is simply to reverse its position. Its curved form issuch that clogging or binding of the refuse substance upon the scraperis prevented when it has been partially loaded.

' I do not limit myself to making this scraperblade curved at anyparticular and exact angle,-but reserve the liberty of making the pitchof the curve variable and in accord with whatever experienee maydictate. Furthermore,

it will be noted that, although my invention is principally serviceablein using a scraperblade having a compound curve, yet it may,

if desired, be used as a simple curvethat is to say, the half of thescraper-blade may be employed instead of the Whole.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a scraper for various uses, a compoundly-curved scraper-blade, incombination with a handle, said blade being affixed to the handle atright angles thereto, substantially as described.

2. In ascraper for various uses, the (30111- poundly-curvedscraper-blade B, having the curved edges a a, in combination with thehandleA and the braces b 12, substantially as described.

3. In a scraper for various uses, the combination of thehandleA, thecompoundly-curved scraper-blade, and the braces for securing said bladeto the handle at right angles thereto, all the parts being arranged sothat the said device may serve as a pulling scraper or as a pushingscraper, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
